android - ionic 2 : What happens during splash screen?
<p><p>我构建了一个 Ionic 2 应用程序，我想知道在应用程序启动屏幕期间究竟发生了什么？ </p>
<p>您能否建议我使用高效的分析工具来分析我的应用的所有性能，即使是在这个闪屏期间？ </p>
<p>我的应用在生产模式下会在 6 秒内初始化(Honor 6x pro)。我觉得太过分了，你觉得呢？</p>
<p>感谢您的帮助! </p>
<p>我的 config.xml</p>

<p>我的 platform.ready 函数:</p>
<pre><code>platform.ready().then(() => {
StatusBar.styleDefault();
Splashscreen.hide();
});

<p><p>使用 <code>ionic build android --prod</code> 构建可以解决问题。大大减少了应用的初始化时间。</p></p>
